Queen breeding and genetics

af
(Udvid)

Breeders and producers of queens need a handbook which describes the background of their work. It can only be done if ou know the techniques of rearing queens and judging the results. You must know the genetics of the bees, too, because it enables you to plan the maintenance and improvements of your stock. The aim of this book is to help the practical people who rear queens. The author has written books and articles of beekeeping since 1983, see www.eigilholm.dk.Content of Queen Breeding and Bee Geneticspreface 51. production of queens 6The basis of queen production 6Methods of queen rearing 7Grafting 8The calendar 8The cell builder 9The breeder colony 10Grafting tools 10Grafting procedure 11Transfer to the cell builder 12Incubation 12How to obtain young bees 14Marking of queens 14Transport cage and candy 16Shipping 172. mating nucs 18How to use the nuc 19Continous management of a nuc 21Clearing after the mating season 213. alternative metods 221.
